HANDLE-BRACKET FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. $572,889, datedFebruary 2'7, 1883.

Application filed October 17. 1878.

To all whom tt may concern:

Be it known that I, ROBERT MCDOWELL LAFFERTY. of St. Paul, in the countyof Ramsey and State of Minnesota, have invented certain new and usefulImprovements in Handle- Brackets for Pumps, which improvements are fullyset forth in the following specification and accompanying drawings, inwhich- Figure I is an inside perspective view of my improved bracket,and Fig. l[ an outside perspective view of the same.

Similar letters denote like parts in both fignres.

This invention relates to pump-handle brackets; and it consists in theconstruction hereinafter particularly described, and then sought to bespecifically delinedby the claim.

I is a U-shaped plate, made either in one or two pieces. and providedwith bearings r, through which the pin passes, and which are connectedto the plate 1 by curved and particircnlar webs or braces t. By thismanner of forming the handle-bracket--viz., by curving or slanting thewebs or braces t-l am enabled to make the parting in the sand, when theyare cast, along the upper edge of the base I, and around the edge t ofthe slot, through which the handle passes, and through the center of thebearings 1', thereby enabling the holes for the pin through the bearingsto be cored out, thus saving the expense and labor of boring. Anotheradvantage resulting from this arrangement is, that by curving the websthey are made much stronger than if they were strong for the purpose forwhich they are intended. They may, moreover, be made of malleable iron,and yet by their lightness be as cheap as ordinary cast-iron. Anotheradvantage is that the bearings a may be lengthened without materiallyaffecting the weight of the metal, which is agreat advantage in somecases.

A small rib, t may be formed upon the under side of the slot, throughwhich the handle passes, .to 'atl'ord additional strength to thebracket, if desired.

I am aware that it is not new to cast U- shaped brackets forpump-handles, and lay no claim broadly to brackets so made; but,

Having described the construction and advantages of myimproved bracket,what I claim as new,and desire to secure byLetters Patent, 1s-

The Ushaped bracket I, having the web t extending out from its base andmade concave on its inside, as shown, and provided with the bearings rat the crown of the web, whereby the bracket can be formed as set forth,for the purpose specified.

in testimony whereofI have hereunto set my hand in the presence of twosubscribing witnesses.

ROBERT MCDOWELL LAFFERTY.
